A hole display refers to a display that has a punch-hole in it.

Not all display panels with a punch-hole are considered a hole display. To be considered as one, the punch-hole must be placed within the active area of the screen. If the hole-shaped cutout is within the bezel (the dead space outside the active area of the screen), it is not referred to as a hole display. If the cutout is placed at the boundary between the active area and the dead space, this is also not a hole display: Instead, it is called a notched display.

A punch-hole located within the display panel is conducive to embedding a sensor that receives light such as a camera.

Production of a hole display requires highly-advanced technologies for patterning display pixels and processing the punch-hole. One of the key technologies used to create a punch-hole in a display is a laser. After the hole is created, the area around the cutout must be encapsulated to ensure that the fine metal circuits and the various emitting materials around the punch-hole are not damaged through exposure to air. Making sure that the hole display doesn’t affect any of the surrounding display resolutions is another important factor to consider.

A hole display, one of the sophisticated technologies enabling the Full screen, offers a more immersive experience to users. This goes beyond smartphones, as the technology application can enable design innovations across various IT devices.
